Freeze Protecting Your System
The installations most prone to freeze damage include systems that have panels below the pool
water level and systems installed in hard freeze locations. All systems, when shut down for the
winter, must be checked to ensure that they are completely drained.
It is suggested to set up a winterization and spring tune-up schedule with your FAFCO Inc.

Systems are not warranted against freeze damage.
If you choose to winterize your system yourself, please follow the steps bellow:
1. Ensure the diverter valve is set to bypass the CoolPV
®
System.
2. Ensure that the pump and filter are not running.
For panels below pool level, item 7 must be done before proceeding to item 3.
3. Open manual drain valves.
4. Remove Vacuum Relief Valve
5. Remove end caps at the lowest panel.
6. Let the system drain completely.
7. Close the isolation valve.
8. Turn on the pool equipment, ensuring that the diverter valve is turned to the thermal off posi-
tion. Let the system run for at least 5 minutes while checking to make sure no water is com-
ing out of the end cap area of the panels.
